The new Wiley journal review system is an absolute nightmare. Editorial assistants have been replaced by a clunky, AI-enabled website that makes it harder to find and invite reviewers. Associate editor workloads have increased. I'm not convinced the invitations to reviewers are even going through.

Later that day I’ll tell you about why dendrobatid poison frogs have the largest and smallest anuran genomes measured to date! 🐸🧬

After lunch, come digest and think about frogs eating toxins — 2:45 today #Evol2025
Tuesday we have two talks. First is Adri Jeckel who will provide an enticing first look at toxin feeding experiments in Epipedobates poison frogs. Can juveniles 👶 sequester as much toxins as adults? Come find out!

"It’s a remarkable quarter-century arc for an infotech company to go from revolutionizing search by using PageRank as a way of prioritizing results from influential and trusted sites, to grabbing any old random bullshit from the web and offering that up to its users in the guise of an AI Overview."
Very pleased that our online course about how to learn and thrive in an online world (thebullshitmachines.com) is mentioned in @johnthornhill.bsky.social's latest Financial Times piece.
